Study on the photoacoustic spectroscopy measurement of methane with different laser bias DC waveforms

Study on the photoacoustic spectroscopy measurement of methane with different laser bias DC waveforms

In dissolved gas analysis of transformers, methane is one of the key indicators for fault diagnosis, thus accurate methane detection means a lot for early transformer failure caused by partial discharge or overheat. Photoacoustic Spectroscopy (PAS) combined with Tunable Diode Laser (TDL) as light so...
